'The Walking Dead' is going to have a big crossover with its spin-off show

Will Rick and Jesus eventually meet someone from "Fear the Walking Dead"? AMC

The INSIDER Summary:

"The Walking Dead" is going to have a big crossover event with its spin-off series "Fear The Walking Dead."

"TWD" creator Robert Kirkman revealed the news at Saturday's New York Comic Con panel for "The Walking Dead."

We don't know when it's happening.

Kirkman said one character from "TWD" or "Fear the Walking Dead" will appear on the other show.

He teased we'll learn more in "the coming months."

After telling fans it was never going to happen, "Fear The Walking Dead" and " The Walking Dead" are going to finally collide in some sort of mysterious crossover.

How it will happen isn't really clear yet.

"What I'm going to say, and this is all I'm going to say, is that there are two 'Walking Dead' shows. I'm not going to name them, but there are two," "The Walking Dead" creator Robert Kirkman told fans Saturday night at the show's New York Comic Con panel. "There is one character that is going to go from one show, that I will not name, and appear in the other show, which I will not name."

The news was met with a lot of cheers from fans. Instead of getting into specifics of what that meant for the two zombie shows, Kirkman got playful with the crowd.

"What does that mean? How does that work?" he asked the room at Madison Square Garden's theater. "Are we going to see an interesting backstory of a 'Walking Dead' character showing up in 'Fear The Walking Dead'?'"

Panel moderator Chris Hardwick interjected for a brief moment before Kirkman told him to allow him to continue to hype the crowd.

"Or are we going to see a 'Fear the Walking Dead' character show up in 'Walking Dead' and see a future version of a character?" Kirkman continued. "What could happen? Is it going to be something completely different? Who knows?"

Hardwick shared his own hope for the mystery crossover.

"I just want the phone to ring and it to be like, 'Daryl, it's your cousin, Madison Clark," Hardwick joked of the spin-off's lead character.

A lot of fans think Madison is related to one of the characters on "The Walking Dead" because we haven't learned her last name. Justina Mintz/AMC

"This is a huge event in the world of the 'Walking Dead,'" said Kirkman as he got serious for a moment. "We're very excited about this and there's going to be some more news on this in the coming months."

"Fear The Walking Dead" takes place in the same apocalypse as the main show, but right after the zombie outbreak begins. Showrunner Dave Erickson previously told INSIDER "Fear" starts off right around the same time as the start of "The Walking Dead" pilot.

"Our starting points are similar," Erickson told INSIDER in 2015. "The first day of our show is around or about the day that Rick was shot and fell into his coma."

Now in its third season, "Fear The Walking Dead" ratings haven't been doing so hot. The show hit a series low in its current season. It could definitely use a little boost from its sister show if a character from "TWD" came over.

Kirkman stressed the shows will continue following their own main stories.

"We want these shows to have their own legs, and tell their own stories, and be their own thing. I think that we've finally gotten to a place with 'Fear the Walking Dead' where we can play with some things," he said.

"The Walking Dead" will kick off its eighth season October 22 at 9 p.m. on AMC. Let us know who you would like to see appear on either show.
